Players report Deathwing still burning the world

I don’t know if it is really still true, but on Mirage raceway some folks were telling they are still seeing flames and that dragon burning the zones.
If it is true, then my question to blizzard: Is it just ignorance level being so high that you don’t even want to accomodate the game accordingly to the story/make it how you did back then? After Dragon soul release and someone killing deathwing there, he should be gone for good from burning the world, but seems to be that blizzard messed up again, if these reports are true. I doubt that there were no guilds able to defeat Deathwing in DS on Mirage raceway to this point of time after release.

Anyways I would like to hear from your experience as well, maybe it is just a fluke or it is still how the game is
